ResumoWe present a review of the Raman spectra of graphite from an experimental and theoretical point of view. The disorder–induced Raman bands in this material have been a puzzling Raman problem for almost 30 years. Double–resonant Raman scattering explains their origin as well as the excitation–energy dependence, the overtone spectrum and the difference between Stokes and anti–Stokes scattering. We develop the symmetry–imposed selection rules for double–resonant Raman scattering in graphite and point out misassignments in previously published works. An excellent agreement is found between the graphite phonon dispersion from double–resonant Raman scattering and other experimental methods.
